Rebooting....

The same chassis with the same interfaces and the same configuration, does not perform any reboot with OS versione 5.1.2. Please note that i noticed the same behaviour with different hardware (another 520 with 3 int) and the same sw and config.

Can you help me??

Thanks in advance. Regards.
